DESCRIPTION
This is my presentation from the Business of APIs Conference in SF, held by Mashery (http://www.apiconference.com).This talk talks briefly about the history of the Netflix API, then goes into three main categories of scaling:1. Using the cloud to scale in size and internationally2. Using Webkit to scale application development in parallel to the flexibility afforded by the API3. Redesigning the API to improve performance and to downscale the infrastructure as the system scalesWhen viewing these slides, please note that they are almost entirely image-based, so I have added notes for each slide to detail the talking points.

Improve Efficiency of API Requests
Could it have been 100 million requests per day? Or less?(Assuming everything else remained the same)
